Abstract
A policy engine for handling incoming data packets. The policy engine includes a stream classification module, a data packet input/output module, and a policy enforcement module. The policy enforcement module further includes a packet scheduler, an on-chip packet buffer circuitry, and a plurality of action processors. The stream classification module creates a packet service header for each data packet, wherein the packet service header indicates policies to be enforced for that data packet. The action processors enforce the policies.
